Maha Season Planting Guide: What to Sow in Sri Lanka from October to March
Maha season has started. From late October through to March, the north-east monsoon gives Sri Lanka its main growing window of the year — more reliable rain, cooler nights, and far less of the scorching that makes April planting such a gamble. This is the season serious home gardeners plan around.
If you have been meaning to start a home garden, this is the easiest time of year to succeed at it. Here is what to sow, when, and what each crop needs.
Why Maha Is the Easier Season
Sri Lanka has two cultivation seasons. Maha runs roughly October to March on the north-east monsoon. Yala runs April to August on the lighter south-west monsoon. Maha gets more rain across more of the island, which means less watering by hand and far fewer plants lost to heat stress in their first fortnight.
For a home gardener that matters more than it sounds. Most beginner failures happen in the first three weeks, when seedlings are small and a single missed watering in dry heat is fatal. Maha forgives that.
The trade-off is too much water rather than too little. Drainage becomes the thing to get right — more on that below.
What to Sow Now: October to November
Plant these as the rains establish. All of them are comfortable in the wet and will be producing by December or January.
- Beans — fast, generous, and among the most reliable crops for a first-time grower. Ready in about 7–9 weeks.
- Brinjal (බටු) — slower to start but keeps producing for months. Brinjal SS seeds are Rs 80.
- Thalana batu (තලන බටු) — hardier than brinjal and well suited to our conditions. Seeds Rs 80.
- Luffa / wetakolu (වැටකොළු) — a climber, so give it a fence or trellis. Luffa Asiri seeds Rs 80.
- Red amaranth / thampala (රතු තම්පලා) — harvest in about four weeks. The quickest win on this list. Seeds Rs 80.
- Leafy greens generally — mukunuwenna, kankun and gotukola all establish easily now and can be cut repeatedly.
What to Sow December to January
As the heaviest rain eases, the cooler weeks open up crops that dislike both heat and waterlogging.
- Tomato — much easier in Maha than in Yala, though still the fussiest thing most people grow. Our tomato growing guide covers feeding in detail.
- Capsicum and chilli — slow starters, long producers. Worth the patience.
- Cabbage, knol khol, beetroot and carrot — these genuinely prefer the cool. In the up-country they do well through most of Maha; in the low country, December and January are your window.
- Radish — three to four weeks from seed to plate. Good for keeping children interested.
- Leeks — slow but undemanding, and expensive to buy, so the saving is real.
Drainage Is the Thing That Will Catch You Out
Maha’s risk is not drought, it is roots sitting in water. Waterlogged roots cannot take up oxygen, and the plant wilts exactly as if it were dry — which leads people to water more and finish the job off.
Three things prevent it:
- Raise your beds. Even 15–20cm above the surrounding ground makes a large difference during a week of rain.
- Open up the soil. Rice husk charcoal at Rs 170 is the cheapest effective amendment for heavy soil. Mix it through before planting, not after.
- Check your pots actually drain. Drainage holes block with compacted soil over a season. Lift each pot and look. A coco peat block and grow bag set at Rs 590 drains far better than most reused buckets.
Feeding Through the Rain
Heavy rain leaches nutrients out of the soil, so Maha plants need feeding more often than you might expect — but in smaller amounts, because what you apply can wash away before roots reach it.
What works:
- Before planting: work cow manure or compost through the bed. Eco Max Bio Bull cow dung pellets (Rs 735) or Eco Agri Natural Organic Compost (Rs 440).
- Prefer pellets to powder now. Pellets release slowly and resist being washed out of the root zone. Eco Max Lusty slow-release pellets are built for this.
- For leafy crops being cut repeatedly: a light dose of Eco Max Green Boost poultry pellets after each harvest.
- Feed little and often. Half the dose at twice the frequency beats one heavy application that the next downpour removes.
If you are unsure how much to apply, our guide on improving soil quality naturally goes through it step by step.
A Realistic First Maha Garden
If this is your first season, resist planting fifteen things. Four or five crops you will actually eat, grown properly, will teach you more and feed you better.
A sensible starting set:
- Beans, for a quick and generous result
- Thampala or mukunuwenna, for something to harvest within a month
- Brinjal or thalana batu, for a crop that keeps giving into next year
- Radish, because fast results keep you going
- One tomato plant, as the challenge
A 30-hole seedling tray at Rs 490 makes germination noticeably more reliable than sowing directly into wet ground, and it is reusable for years.
If you would rather not assemble the pieces yourself, the Beginner Home Garden Kit (Rs 1,699) and the Family Vegetable Patch Kit (Rs 4,999) are put together for exactly this season, with the quantities already worked out.
Don’t Wait for a Perfect Week
The most common reason a Maha garden never happens is waiting for the right weekend. The rains do not wait, and every week you delay in October is a week less of growing before March.
Prepare one bed or four pots this weekend. Sow the fast crops first so you have something to show for it within a month. Add the slower crops as you go.
